The following measures are often used clinically for the prevention of surgical incision infections: First, half an hour before the start of surgery, the incision can be prevented from becoming infected by intravenous infusion of antibiotics such as cefmetazole or cefamandole. If the duration of surgery is more than 3 hours, an additional group of antibiotics is needed intraoperatively, which can improve the concentration of antibiotics in the patient’s blood and better prevent incisional infection. Second, at the end of surgery to perform wound suturing, it is necessary to use sterilized saline to thoroughly rinse the wound to avoid excessive residual local bacteria and necrotic tissue, which can cause infection of the incision. Third, the tension of the silk thread when suturing the incision should not be too great to avoid poor blood circulation at the incision and fat liquefaction or infection. Every time the wound dressing is changed, the wound needs to be thoroughly cleared and disinfected, and 75% alcohol gauze can be applied to the wound if necessary, which can also effectively prevent wound infection.
